Talk to Jim Straicha up there…every resort owner knows him…he pulls stuff out of the lake that falls thru. He has a scrap yard and likes anything with metal.

Still trying to figure out the quote function….Ron is the winner!

We just had our bathroom remodeled and I experienced something similar today. They ran a new stack which connected our toilet and tub venting….flushed the toilet and the tub gurgled. Went out back to check the vent pipe on the roof and it was blocked with snow/ice Cleaned them up and have not had an issue. Hope your fix is an easy one.
